多因素数学模型在温州瓯江口浅滩围涂工程研究中的应用

建立了波浪、潮流、盐度、悬沙、底床冲淤等多种因素数学模型,在模型验证的基础上,对瓯江口温州浅滩围涂工程海区的波浪场、潮流场、盐度场、悬沙场、底床冲淤场进行了数值模拟研究,对温州浅滩围涂工程对瓯江泄洪、瓯江南北口分流比、乐清湾养殖业、瓯江口港口航道及状元岙深水区、南口口外滩地的影响进行了分析论证。分析研究结果表明,温州浅滩围涂工程是可行的。

Application of Multi-elements' Mathematical Model in the Study on Reclamation of Wenzhou Shoal at Oujiang Estuary

Mathematical models of multi-elements, i.e. wave,tidal flow,salinity,suspended sediment and seabed erosion and siltation,are set up. On the basis of model verification and calibration by field data,wave field,tidal flow field,salinity field,suspended sediment field and seabed erosion and deposition field of Oujiang Estuary,where large-scale reclamation project of Wenzhou Shoal will occur,are numerically simulated. According to the results,of which the influences of reclamation project on the flood discharge of Oujiang River,on the splitting ratio of the north branch and south branch of Oujiang Estuary,on the aquatic product breeding industry of the Yueqing Bay,and on the harbors and navigation channels at Oujiang Estuary are demonstrated. The result of study proves that the reclamation project of Wenzhou Shoal is technically feasible.
